This invention relates lto an improvement in shoe forms and moreparticularly in-expansible toe forms adapted to be insertedA into thetoe of a shoe and expanded therein to 5 plump out the shoe and put it-in the ideal condition for display .orl other purposes,"y

Various types of such toe forms -have been proposed `and suggestedheretofore and the object of the present invention is to .provide lc animprovement upon the means for expanding'and contracting the4 toe-formsuch `improvement including a crossbrace made vinto en being insertedinto or withdrawn fromVA the Other objectsof` the-invention reside fr inthe` provision of the; particular structural features set-,forth in thefollowing descrip- 25V tion and illustrated in the accompanying drawingswherein y Y v Fig. 1 .is a sideelevation ,of a toe form embodying thisinvention; 9j. i

The bars` 16 andfl are preferably of Celluloid which-'10 may belaminated asv shown inFigs.l Land v5. The .shoulder 25 isformed on theupperlamina 30 which projects beyond thelower lamina -31 whilethe ledge26 is formed bv thelower lamina 32 which stops short of' the upper'llamina `33. Iherivet 20 extends through the Yupper laminae 30 and 33. fOther ways of forming the-shoulder' 25 and thev ledge26 and of joiningthe barsmay of course be-.employed, those herein described havingbeenkvO` selected for the purpose of illustration and It will be.apparentthat when the retractor 21is pulled to the left in Fig. 1 theform f isrcontracted:k as in Fie. 3 until the ortion.85 Figs. 6 and 7are views corresponding to t p n 26. The form is-nowK in condition tobefinserted into or withdrawn from the toeof a expanded positionillustrated in F ig.`2 with the portion 28 of the shoulder in` contactwith `-the ledge 26.
